It features a 17\/32-inch inside diameter and a 3\/4-inch body outside diameter, with a 1\/2-inch length under the head. Constructed from steel hardened to 60 to 65 HRC, this bushing delivers consistent bore alignment and long service life under repeated drilling cycles. It is a permanent, non-renewable installation intended for production or tooling setups where a fixed guide is required.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixtures, and tooling plates in metalworking and machining environments. It is installed by press fit directly into a prepared hole in the jig plate, making it appropriate for applications where the bushing will remain in place for the life of the tool. Machinists, toolmakers, and fixture builders working in production shops, job shops, or manufacturing facilities are the primary installers. The head style seats flush against the jig plate face, preventing the bushing from being pushed through during drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H headed press fit bushing per ANSI standards\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 17\/32 inches with a tight tolerance of +0.0001 to +0.0005 inches for accurate drill guidance\u003c\/li\u003e\n  \u003cli\u003eBody outside diameter of 3\/4 inches and head outside diameter of 59\/64 inches\u003c\/li\u003e\n  \u003cli\u003eHead height of 7\/32 inches provides positive seating against jig plate surface\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for wear resistance in high-cycle drilling\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design for permanent fixture installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-compliant Type H press fit headed drill bushing for use in standard drill jig plates and tooling fixtures with a prepared 3\/4-inch body bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using a press to drive the bushing into a precisely reamed jig plate hole. The receiving hole must be machined to the correct interference fit tolerance before pressing to avoid damage to the bushing or plate. Do not use impact tools or hammers directly on the bushing head. Always verify inside diameter clearance against the intended drill bit or tool shank before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 17\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 59\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BONEHAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H488LR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51728448389426,"sku":"H488LR","price":20.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_4467d7b6-5b48-4ccd-b421-4c60c2cb90ea.jpg?v=1788691345","url":"https:\/\/voomisupply.com\/products\/boneham-h488lr-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
